What it means
The invoice can name the seller's tax representative (BG-11), the person or company the seller has appointed to account for VAT on its behalf. In UBL a postal address can carry the name of the block it lies in, meaning an area surrounded by streets that usually holds several buildings. EN 16931 has no separate field for it, because the address is given as address lines, city, postcode, country subdivision and country. The rule fails when cac:TaxRepresentativeParty/cac:PostalAddress/cbc:BlockName is in the file at all, even if empty.
Why it matters
EN 16931 does not use a separate block name field for the tax representative's address. A block name can be included in an address line if needed.
How to fix it
If you need the block name in the address, include it in an address line, such as the second address line (BT-65), cbc:AdditionalStreetName. Remove cbc:BlockName from cac:TaxRepresentativeParty/cac:PostalAddress and recheck the corrected file.
